These 16" x 18" x .003 white patch handle reinforced poly bags with a 3" bottom gusset are a reusable bag based on most municipal plastic bag ordinances. They are being used in grocery stores in the City of Chicago. They are made in the USA and are completely recyclable at the end of their life span.
